MACHINE FOR TEMPERING CLAY.

Specification of Letters Patent No. 24,350, dated June 7, 1859'.

To aZZ whom it may concern:

Be it known that I, J. D. CUSTER, of Norristown, in the county ofMontgomery and State of Pennsylvania, have invented a new and usefulImprovement in Machinery for Tempering Clay and for other Similar andAnalogous Purposes; and I do hereby declare that the following is afull, clear, and eXact description of the same, reference being had tothe annexed drawings, making a part of this specilication, in which-Figure l, is a vertical section of my invention taken in the line w,Fig. 2. Fig. 2, is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to an improvement in that class of machines whichare used for tempering clay and for similar or analogous purposes andwhich machines are composed of a wheel placed on a radial shaft and madeto rotate within a circular pit.

The within described invention relates to an improvement in driving orpropelling the `wheel as hereinafter fully shown and described, wherebypower other than animal, such as water and steam may be applied to themachine in a very simple and economical way and in a manner much lesscalculated to injure or rack the working parts than hitherto, therebyenabling me to construct a strong and durable machine much lesscumbersome than usual and one that may be driven or operatedl with asmaller expenditure of power.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a circular pit which may be of any suitable depth anddiameter, and B, is a vertical shaft, the lower end of which is forkedand connected to a journal C, which is stepped at a, at the center ofthe pit, the upper end of shaft B, having its bearing in a plateattached to a cross plate Z), of a framing D. In the fork at the lowerend of the shaft B, a bar E, is fitted and secured by the same pin orbolt c, that secures the shaft B, to the journal C. To the bar E, a rodor shaft F, is attached and on this rod or shaft a wheel G, is fittedloosely and allowed to rotate freely. The bar E, is allowed to work orplay in a vertical plane on the pin or bolt c.

H, is a frame the inner end of which is fitted loosely on the shaft B,and on the journal C. To the outer end of thisv frame H, two plates d,cZ, are attached, said plates forming the bearings fora shaft I, whichhas a plate J, fitted loosely to it. On the .upper end of the shaft VI,a pulley K, is fitted or attached and a belt e, passes around thispulley and around a pulley f, which is attached to a hollow shaft g,that is placed loosely on the shaft B, above the frame H. On the upperpart of the shaft g, a pulley 7L is attached, and this pulley has a beltz', passing around it, which belt also passes around a pulley j, on ahorizontal shaft L, in the framing D. On the shaft I, a pinion k, isplaced, and this pinion gears into a toothed wheel M, on the upper partof a shaft N, said shaft being attached to the plate J, and having apinion Z, on its lower end which pinion gears into an annular toothedrim O, which encompasses the pit A. The outer end of the rod or shaft F,is connected by a rod P, with the plate J. To the plate J, guide rollersm, m, are attached which rollers bear or work on the rim O, a similarroller n, is attached to the frame H. To the shaft B, a horizontal armQ, is attached and to the outer end of this arm a curved rod B, isattached, said rod projecting upward and within the belt e.

The pit A, and also the framing may be constructed in any of the knownways and the gearing k, M, Z, and also the pulleys K, j", h, j, may beof such relative proportion or size as may be required.

The power is applied to the shaft L, and motion is communicatedtherefrom to the hollow shaft g, by the belt z', and from the shaft g,motion is communicated to the shaft I, at the outer end of the frame H,by the belt e. The shaft N, is operated from s'haftI, by means of thegearing 7c, M, and as the pinion Z, on shaft N, gears into the rim O,the frame H, will be moved or rotated on the shaft B, and as the rod orshaft F, is connected to the plate J, by the rod P, the wheel G, will berotated' within the pit A.

It will be seen therefore from the above description that the power isapplied to the outer end of the rod or shaft F, of wheel G, andconsequently said rod or shaftvwill not be subjected to any undue strainas it is well supported. The reverse would be the case were the powerapplied to the inner ,end as the resistance of the moistened clay orother substance in A, would make to the movement of the wheel G, wouldbevery trying to its shaft. Besides the power could not be applied to a.central shaft without considerable expense. In case the rod or shaft F,should become casually detached from the plate J, of frame H, the belte, which drives the latter will be cast 0E, by the rod R,`which inconsequence of its inclined position and the cessation of its 1novementin connection with its relative position with the belt e, effects theresult. In

. consequence of having the bar E, pivoted in the fork of the shaft B,the wheel Gr, as it rotates and moves around in the pit A, is allowed torise and fall so as to yield to a certain extent to the clay or othermaterial within the pit.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is,

The arrangement and combination of the stationary toothed rim O,encompassing the pit A, the frame H, witluthe gearing lc, M, Z, attachedto its outer euch-the pinion Z, of the shaft N, gearing intothe rim0,and the rod or shaft F, connected with the frame H, the hollow shaftg, on shaft B, and the belts e, i, passing around the pulleys K, f, 7L,j, substantially as and for the purpose set forth.
